Hi Anthony, > Oh OK, I think I understand a little better.

Thanks. This is the idea I had, but was failing to implement (although I didn't use walkNodes). To get it to work, I had to figure out how to use createEArray properly. In the end, it was a silly fix. I created an EArray with shape (0,96,1,2), and was trying to append numpy arrays of shape (96,1,2) to this, which was failing. In the end, all I had to do was arr.append(np.array([my_array])) where as before, I was simply missing the "[ ]" brackets, so the shapes did not line up.
